Question

If it takes 2 whole cups of chocolate chips to make 100 cookies, how many cups of chocolate chips do you need to make 25 cookies?

Answer 1

1/2 a cup will make 25 cookies because 1 cup makes 50 cookies and 2 cups makes 100 cookies

Answer 2

1/2 cup

Explanation:

We can use ratios to solve

2 cups x cups

--------------- = ----------------

100 cookies 25 cookies

Using cross products

2 *25 = 100x

50 = 100x

Divide by 100

50/100 = x

1/2 = x
